WebA stationary distribution of a Markov chain is a probability distribution that remains unchanged in the Markov chain as time progresses. Typically, it is represented as a row vector \pi π whose entries are probabilities summing to 1 1, and given transition matrix \textbf {P} P, it satisfies. \pi = \pi \textbf {P}. π = πP.
